Finite ele ment analysis on 3D freezing te mperature field in metro connected aisle construction
摘要
Abstract
Artificial freezing method has been widely applied in connected aisle construction in metro.Predictive analysis on stratum freezing temperature field can determine development status of frozen wall and evaluate ration-ality of freezing scheme in advance.The frozen pipes are generally designed as inclined radial shape in metro connected aisle construction with the use of freezing method.The current analysis on freezing temperature field of connected aisle has been mostly simplified to the plane problem,which is difficult to reflect the actual situation. For this reason,connected aisle construction using freezing method in a interval of Shanghai Metro Line No.1 3 is referenced.With the consideration of various initial and boundary conditions such as ground temperature,surface convection and freezing phase change latent heat,etc,3D finite element numerical model is presented.Distribu-tions of the 3D stratum freezing temperature field are systematically analyzed during active freezing period of the connected aisle,which are compared with field measured results to verify the reliability of finite element numeri-cal analysis.关键词
